When we run our kernel from a notebook the kernel gets a “comm_open” request with widget class “ipywidgets.CommInfo”, target name “ipython.widgets”.
What do we do with this?
Can I safely ignore this message and any other comm_open messages? Should I respond to any comm_open messages with a comm_close as suggested in the docs (“If the target_name key is not found on the receiving side, then it should immediately reply with a comm_close message to avoid an inconsistent state.” But it’s unclear what the “target_name key is not found on the receiving side” means).
